Chinese President Xi Jinping and Indian Prime Minister Narendra Modi are unlikely to meet on the sidelines of the G20 summit, with Beijing saying that "the atmosphere is not right" due to their border stand-off. India clarifies there was no one-on-one planned.

"The atmosphere is not right for a bilateral meeting between President Xi and Prime Minister Modi," a Chinese Foreign Ministry official said. The Foreign Ministry said that the "trespass" by Indian troops into Chinese territory "had damaged the political foundations of bilateral relations between China and India.

"As for the arrangement of the bilateral meeting (at G20) between President Xi and Prime Minister Modi, I have to point out that recently Indian troops trespassed into China and obstructed normal activities of Chinese troops in Doklam region," said Foreign Ministry spokesperson Geng Shuang.

"This endangers China's sovereignty and territorial integrity and damaged the political foundations of bilateral relations between China and India. Regarding the bilateral meeting of President Xi and PM Modi, we will release it in a timely manner," Geng added.

"We hope India can immediately withdraw the border troops to the Indian side of the boundary and uphold peace and tranquillity of the China-India border areas. I think this is the pre-condition for any meaningful peace talks between the two sides." Geng warned that India would have to face "serious consequences" if it did not withdraw troops from Doklam.

"Under the pretext of protecting Bhutan, India has illegally entered China's territory hindering negotiation process between China and Bhutan," the official added.
